There's no such thing as too many processes, there's only having errant and/or unwanted processes.
The number of processes you have running depends entirely on the programs you have running. 75-80 might be excessive, and it might also be perfectly normal. Every system will be different due to the number of programs the user has running. Having more than a specific number of processes is NOT necessarily the result of a virus and/or malware.
If you're concerned however, type in the name of each process into Google and see what comes up.
I have Vista and if you go into Task Manager and it says you have 78 processes running, what does that mean?
Someone told me if you have too many that means you have a virus,
I usually have about 75-80 running
There is a button where you can end each process, can't I just do that?
I hope I am making sense in my question
Thanks in advance.
